Robert Lockman Sr. was 9 years old when he borrowed the children’s book, “Val Rides the Oregon Trail” from Osterhout Free Library in Wilkes-Barre, Pennsylvania, in late 1941. The book was due Dec. 2, 1941, but Lockman never returned it. But 75 years, 2 months and 13 days later, his son, Robert Lockman Jr., brought the book back into the Osterhout Library.

“I thought it would be the right thing to do,” he told the Scranton Times-Tribune on Wednesday. “My dad was an honest guy. That’s what he would have done.”

But what about those late fees? The library estimated that at the 1941 rate of 2 cents for each day overdue, the fine would be about $554. But the librarians waived the fee.
